Why and How Should We Assess the Cardiovascular Risk in Patients with Juvenile Idiopathic Arthritis? A Single-Centre Experience with Carotid Intima-Media Measurements.

BACKGROUND: Children diagnosed with juvenile idiopathic arthritis (JIA) are thought to be more likely to develop cardiovascular disease in adulthood. The factors modulating the cardiovascular risk, involving exposure to secondhand smoking, sedentary lifestyle and abnormal body mass index, might have had a stronger impact during the COVID-19 pandemic. The lack of reliable prognostic markers for a higher probability of cardiovascular events might be solved by carotid intima-media thickness (cIMT) measurement. The paramount goal of the study was to assess its usefulness in JIA patients. MATERIALS AND METHODS: The results of cIMT measured by a single physician in 45 children diagnosed with JIA were compared to 37 age- and sex-matched healthy counterparts. The analysis also involved anthropometric parameters, laboratory tests, and a survey regarding lifestyle-related factors. RESULTS: Four JIA patients appeared to have cIMT above the 94th percentile. A positive correlation between erythrocytes sedimentation rate (ESR) and right carotid artery percentiles was found. Passive smoking increased the cardiovascular risk regardless of JIA. Doubling the daily screen time during the pandemic led to a significant reduction in children's physical activity. However, the number of enrolled subjects was not enough to make significant recommendations. CONCLUSIONS: cIMT measurements remain an interesting perspective for future cardiovascular screening of children with JIA. It has yet to be determined whether it should be considered in all JIA patients on a reliable basis.

Ultrasound findings in severe COVID-19: a deeper look through the carotid arteries.

Objective: To investigate vascular and perivascular abnormalities in the carotid arteries using ultrasound, as well as to evaluate their association with mortality and clinical variables in hospitalized patients with coronavirus disease 2019 (COVID-19). Materials and Methods: This was a prospective study in which 53 hospitalized patients with severe COVID-19 were evaluated and underwent carotid ultrasound. We documented the carotid ultrasound findings in these patients. Clinical, demographic, laboratory, and imaging features were analyzed and compared by statistical analysis to detect correlations between them. Results: Carotid ultrasound demonstrated luminal surface irregularity in 29 patients (55%), carotid plaques in 30 (57%), perivascular infiltration in four (8%), and increased intima-media thickness (IMT) in 31 (58%). Of the 31 patients with increased IMT, 19 (61%) died, and the association between increased IMT and COVID-19-related mortality was significant (p = 0.03). Logistic regression showed that the risk of death was 85% in patients who had increased IMT in combination with acute kidney injury at admission or a history of chronic kidney disease (p < 0.05). Conclusion: In hospitalized patients with severe COVID-19, carotid ultrasound can show increased IMT, luminal surface irregularity, carotid plaques, and perivascular infiltrates. The combination of increased IMT and kidney damage appears to increase the risk of death in such patients.

Objetivo: Investigar anormalidades vasculares e perivasculares nas artérias carótidas por meio de ultrassonografia e avaliar sua associação com mortalidade e variáveis clínicas em pacientes hospitalizados com COVID-19. Materiais e Métodos: Neste estudo prospectivo, 53 pacientes hospitalizados com COVID-19 grave foram avaliados e submetidos a ultrassonografia de carótida. Descrevemos os achados ultrassonográficos de carótida nesses pacientes. As correlações de características clínicas, demográficas, laboratoriais e de imagem foram analisadas e comparadas por meio de análise estatística. Resultados: A ultrassonografia carotídea demonstrou irregularidade da superfície luminal em 29 pacientes (55%), placas carotídeas em 30 pacientes (57%), infiltração perivascular em quatro pacientes (7,5%) e aumento da espessura médio-intimal (EMI) em 31 pacientes (58%). Dos pacientes com EMI aumentada, 19 (61%) morreram, com associação observada entre EMI aumentada e mortalidade por COVID-19 (p = 0,03). Um modelo de regressão logística mostrou que a probabilidade de óbito foi de 85% em pacientes com EMI aumentada e história de nefropatia crônica ou lesão renal aguda na internação (p < 0,05). Conclusão: Aumento da EMI, irregularidade da superfície luminal, placas carotídeas e infiltrados perivasculares foram encontrados na ultrassonografia carotídea em pacientes hospitalizados com COVID-19 grave. O aumento da EMI associado a danos nos rins pode aumentar o risco de morte.

Vascular phenotyping in post-COVID children and adolescents-the lico study

Background and Aim: An infection with SARS-CoV-2 is associated with systemic inflammation, that also affects the endothelium. This may result in endothelitis, which can influence vascular regulation and morphology. Until now, the specific mechanism of vessel damage after a SARS-CoV-2 infection is still unclear, especially in children and adolescents. The LICO Study (Long term impact of COVID-19) aims to investigate the long-term effects of a SARS-CoV-2 infection on vascular structure and function in chil-dren and adolescents. Method(s): Children and adolescents with confirmed evidence of survived SARS-CoV-2 infection are screened 6 +/- 3 months post-infection. Vascular function is assessed by flow-mediated vas-odilation (FMD) and aortic pulse wave velocity (PWV). Carotid intima-media thickness (cIMT) and retinal diagnostics (arteriove-nous ratio-AVR) are used to examine vascular structure. The matched control group without prior SARS-CoV-2 infection undergoes the same examination procedure. Result(s): So far, we have been able to evaluate 24 (9 post-covid) subjects (13.5 +/- 1.9 years;9 girls). Compared to the mean refer-ence values of the control group, 5 post-covid subjects have higher cIMT (0.49 +/- 0.01 mm vs. reference value 0.46 +/- 0.03 mm). Of these, 3 post-covid subjects even deviate from the norm PWV (4.96 +/- 0.16 m/sec vs. reference value 4.63 +/- 0.29 m/sec). The same 3 post-covid subjects are also below the norm FMD (2.06 +/- 1.05 % vs. reference value 4.18 +/- 7.04 %). None of the post-covid subjects deviates from the norm AVR values (refer-ence value 0.85 +/- 0.07). Conclusion(s): It is shown that infection with SARS-CoV-2 has the potential to impair vascular regulation. These initial results provide trends for early vascular changes among children and adolescents after recovered SARS-CoV-2 infection. Due to that this is an ongoing study, the results are constantly being expanded and may still change. To determine lasting changes in morphology, the examination is repeated after 6 months and the further results of this longitudinal study must be awaited.

HOW CAN WE ASSESS CARDIOVASCULAR RISK in PATIENTS with JUVENILE IDIOPATHIC ARTHRITIS? PRELIMINARY RESULTS REGARDING MEASUREMENTS of CAROTID INTIMA-MEDIA THICKNESS during the COVID-19 PANDEMIC

Background: There is growing body of evidence that adults who were diagnosed as children with juvenile idiopathic arthritis (JIA) have signifcantly increased risk of developing cardiovascular disease. Risk factors including prolonged sedentary screen time, insufficient physical activity and unhealthy diet are even more essential in the era of the COVID-19 pandemic. However, there is lack of simple and reliable prognostic marker identifying children at higher risk of early development of cardiovascular disease. Non-invasive tests utilized in adults to screen for early phase of atherosclerosis involve examination of the carotid intima-media thickness (cIMT). Only a few research projects have evaluated performance of cIMT measurement in JIA patients and the results remain inconclusive. Objectives: The aim of this study was to evaluate the usefulness of cIMT testing as a screening method to determine cardiovascular risk in JIA patients. The secondary objective was to assess the frequency of risk factors related to the patients' lifestyle during the COVID-19 pandemic. Methods: The study involved forty-five patients at mean age 13.4±3.2 years who were already diagnosed with JIA and thirty-seven age-and sex-matched healthy controls. Children were enrolled in the study between March 2020 and September 2021. Study database included demographic data, conventional risk factors for developing cardiovascular disease (e.g. abnormal body mass index and exposure to secondhand smoking), infammatory markers and disease activity score. Measurements of cIMT were performed by a qualifed physician according to the standardized protocol using high resolution ultrasonography. Results: Measurement of cIMT revealed values above 94th percentile in four children (three males and one female) who were all diagnosed with JIA. The quantity of abnormal results was not enough to verify the hypothesis of increased cardiovascular risk in JIA patients, though (p=0.06296). However, children diagnosed with JIA are more likely to have abnormal body mass index than their healthy peers (51.1% vs. 21.6%, p=0.00614). Children who doubled their sedentary screen time during the COVID-19 pandemic skipped the sufficient physical activity (p=0.03352). Correlation between elevated ESR and higher cIMT values in right carotid artery was marginally signifcant (r=0.292, p=0.051443). Regardless of JIA, exposure to secondhand smoking was proved as a signifcant risk factor of atherosclerosis (18.2% vs. 2.8%, p=0.02771). Conclusion: Screening measurements of cIMT should be considered in the follow-up of JIA patients with higher disease activity with concurrent elevated ESR. Defning other indications for performing such examination requires further investigation involving larger study group. Healthy lifestyle, including reducing secondhand smoke exposure, needs to be promoted with utmost importance during the COVID-19 pandemic, especially in children with chronic diseases like JIA.

Healthy lifestyle changes favourably affect common carotid intima-media thickness: the Healthy Lifestyle Community Programme (cohort 2).

Common carotid intima-media thickness (ccIMT) progression is a risk marker for cardiovascular disease (CVD), whereas healthy lifestyle habits are associated with lower ccIMT. The objective of the present study was to test whether a healthy lifestyle intervention can beneficially affect ccIMT progression. A community-based non-randomised, controlled lifestyle intervention was conducted, focusing on a predominantly plant-based diet (strongest emphasis), physical activity, stress management and social health. Assessments of ccIMT were made at baseline, 6 months and 1 year. Participants had an average age of 57 years and were recruited from the general population in rural northwest Germany (intervention: n 114; control: n 87). From baseline to 1 year, mean ccIMT significantly increased in both the intervention (0⋅026 [95 % CI 0⋅012, 0⋅039] mm) and control group (0⋅045 [95 % CI 0⋅033, 0⋅056] mm). The 1-year trajectory of mean ccIMT was lower in the intervention group (P = 0⋅022; adjusted for baseline). In a subgroup analysis with participants with high baseline mean ccIMT (≥0⋅800 mm), mean ccIMT non-significantly decreased in the intervention group (-0⋅016 [95 % CI -0⋅050, 0⋅017] mm; n 18) and significantly increased in the control group (0⋅065 [95 % CI 0⋅033, 0⋅096] mm; n 12). In the subgroup, the 1-year trajectory of mean ccIMT was significantly lower in the intervention group (between-group difference: -0⋅051 [95 % CI -0⋅075, -0⋅027] mm; P < 0⋅001; adjusted for baseline). The results indicate that healthy lifestyle changes may beneficially affect ccIMT within 1 year, particularly if baseline ccIMT is high.

Liraglutide Improved Cardiometabolic Parameters More in Obese than in Non-obese Patients with Type 2 Diabetes: A Real-World 18-Month Prospective Study.

INTRODUCTION: The glucagon-like peptide-1 agonist (GLP1-RA) liraglutide is currently approved for the treatment of both obesity and type 2 diabetes (T2DM). We investigated whether the effect of this agent on cardiometabolic parameters in subjects with T2DM varied in relation to the concomitant presence of obesity. METHODS: One hundred thirty-five subjects (78 men and 57 women; age: 62 ± 10 years) naïve to incretin-based therapies were treated with low-dose liraglutide (1.2 mg/day) as an add-on to metformin for 18 months. Patients were divided into two subgroups based on their body-mass index (BMI): (a) obese (BMI ≥ 30) and (b) non-obese (BMI < 30). Clinical and laboratory analyses were assessed at baseline and every 6 months. RESULTS: During follow-up, significant improvements were seen in both groups in fasting glycemia, glycated hemoglobin, waist circumference, and carotid intima-media thickness (cIMT), while body weight, BMI, total cholesterol, and low-density lipoprotein cholesterol decreased significantly in obese subjects only. Correlation analysis revealed that changes in subclinical atherosclerosis (assessed by cIMT) were associated with changes in triglycerides (r = 0.488, p < 0.0001) in the obese group only. CONCLUSION: Liraglutide had beneficial actions on glycemic parameters and cardiometabolic risk factors in both non-obese and obese patients with T2DM, with a greater efficacy in the latter. These findings reinforce the benefits of liraglutide for the cardiometabolic outcomes of obese patients with T2DM in the real-world setting. This has critical importance during the current pandemic, since patients with diabetes and obesity are exposed globally to the most severe forms of COVID-19, related complications, and death.
